Sewer line problems don’t happen overnight. They start small—maybe a slow drain here or a strange gurgling noise there—but if left unchecked, they can turn into messy, expensive repairs. Many homeowners don’t realize there’s an issue until they’re dealing with sewage backups or foul odors creeping through the house. But by recognizing the warning signs early, you can take action before things spiral out of control.
Slow Drains That Keep Getting Worse
A slow drain here and there might not seem like a big deal, but when it keeps happening, it could be a sign of something more serious lurking in your sewer line. At first, you might notice water taking a little longer to empty from your sink or tub. You might brush it off, thinking it’s just a minor clog, and reach for a plunger or a drain cleaner. But if the problem keeps coming back or spreads to multiple drains—you could be dealing with something bigger than just a little buildup.
Sewer lines carry all the wastewater from your home to the main sewer, and when there’s a blockage forming deep in the line, it slows everything down. What starts as a sluggish sink could soon turn into a bathtub that won’t drain or a toilet that takes forever to flush. If you ignore the issue long enough, a full blockage can cause sewage to back up into your home.
While minor clogs in a single drain are common, slow-moving water throughout your home could mean tree roots, grease buildup, or even a collapsed sewer pipe is blocking the flow. Pay attention to how long your drains take to empty, and if they’re all acting up at once, it’s time to take a closer look at what’s happening beneath your home.
Strange Gurgling Noises
If your drains are making unusual noises, that’s not normal. A gurgling sound coming from your toilet, shower, or sink can mean that air is trapped somewhere in your plumbing. Normally, wastewater should flow smoothly through the pipes, but when there’s a blockage, the air gets stuck and needs to escape. That’s when you start hearing those odd bubbling or gurgling noises.
This sound is more than just annoying—it’s an early warning that your sewer line isn’t working the way it should. You might notice it most after flushing the toilet or pulling the plug in your kitchen sink after doing dishes. In some cases, one drain can cause another to make noise, like flushing a toilet and hearing a bubbling sound in your shower. This is a red flag that something is blocking proper airflow in your plumbing.
Ignoring gurgling noises can lead to bigger problems, including full-on backups. The longer a clog sits in the sewer line, the more pressure builds up. Eventually, that blockage can push waste and water back up into your home. If your pipes are making noises they never used to, it’s a good idea to have a professional check things out before the problem gets worse.
Unpleasant Odors Coming From Drains
Sewer gas has a distinct smell—something between rotten eggs and decaying waste. If you’re catching whiffs of something foul coming from your drains, don’t ignore it. Sewer lines are sealed systems, meaning that smells shouldn’t be escaping into your home. When you start smelling sewage, it often means there’s a crack, leak, or blockage somewhere in a pipe.
A properly working sewer system uses water traps to block odors from rising up into your home. But when there’s a clog, sewer gases can’t vent the way they should, and instead, they seep back through the pipes. You might notice it most when you run water or flush the toilet. The worse the blockage gets, the stronger the smell becomes.
In some cases, sewer odors could point to a break in the line, especially if the smell is stronger outside in your yard. A damaged or collapsed pipe can let wastewater leak into the ground, causing a lingering sewer stench. Whether inside or outside, persistent sewer smells are never normal and usually mean something in your system needs attention.
Patches of Extra Green Grass in the Yard
Your yard can give you clues about what’s happening underground. If you’ve noticed one patch of grass growing greener and faster than the rest, it could be due to a leaking sewer line.
When a sewer pipe cracks or breaks, wastewater seeps into the soil. While that sounds gross, the nutrients in the waste act like fertilizer, making plants grow thicker and greener in that area.
Beyond just looking different, a leaking sewer line can also create soft, mushy spots in your yard. If the ground feels unusually wet even when it hasn’t rained, it could mean wastewater is escaping beneath the surface. Left unchecked, this can lead to sinkholes, foundation damage, and more costly repairs down the line. If your lawn is showing signs of unusual growth or soggy patches, it’s worth having a plumber check your sewer line for leaks.
Frequent Toilet Backups
Every once in a while, a toilet might clog from too much toilet paper or an object getting flushed. But if your toilet is backing up regularly, especially without an obvious cause, there could be a blockage deep in the sewer line.
When a sewer line is clogged, wastewater has nowhere to go. Instead of flowing out to the main sewer, it reverses direction and comes back up into your home. In many cases, toilet backups are one of the first signs of a sewer issue because toilets directly connect to the main line.
If multiple toilets in your home are clogging at the same time, or you’re seeing waste come up in the shower or sink when you flush, that’s a clear sign of a serious problem. At that point, plungers and drain cleaners won’t be enough to fix it. The sooner you address it, the better chance you have of avoiding messy and expensive repairs.
Insects and Rodents Appearing Indoors
Sewer problems don’t just affect your plumbing—they can also attract unwanted pests. Rats, cockroaches, and drain flies love damp, waste-filled environments, and a damaged sewer line provides the perfect home for them.
If you’re suddenly seeing more insects or rodents inside your home, it might not just be bad luck. A cracked sewer pipe can create openings where pests can enter, making their way up through your drains and into your living space. Drain flies, in particular, breed in standing water and organic waste, so if you’re noticing tiny flies buzzing around your sink or shower, it could mean there’s a clog or backup somewhere in the line.
Rodents are another concern. Since sewers are connected to larger city drainage systems, a broken pipe can give them an easy path from the underground tunnels straight into your home. If you’re dealing with a sudden increase in pests along with other sewer-related problems, it might be time to have your system checked.
